Abstract
A pulse generating implantable medical device comprises a power source , a control unit, a plurality of switching units, a timing unit, a pulse generating unit adapted to generate one or more stimulation pulses to be applied to human or animal tissue via one or more stimulation electrodes, and a coupling capacitor in series with each stimulation electrode. A stimulation pulse is adapted to be applied during a stimulation pulse timing cycle that includes a stimulation phase and a recharge phase, and that the timing of a stimulation pulse timing cycle is controlled by the control unit via the timing unit and the switching units. The implantable medical device further comprises an energy storage unit and that, during the recharge phase, one or more of the switching units is adapted to establish electrical connection between the one or many stimulation electrodes and the energy storage unit in order to collect and store energy from applied stimulation pulses.
